[CLI]: Place Wipe Tower before Slicing

Browse Source 
A plain CLI slice ran none of the placement sites, so a stored or
default tower position that no longer fits the tower the plate needs
went straight to the generation-time error. The slice loop now applies
the same clamp the GUI applies on reload to every plate it is about to
slice, skipping only plates that print no tower: by-object plates with
more than one instance, and plates whose footprint estimate is empty
(which covers single-filament plates without smooth timelapse, wrapping
detection or a raft). The plate's filaments come from the same
config-driven derivation the estimate uses everywhere else.

The two arrange sites read the brim width from the right option when
padding the default position; an auto brim uses its 8 mm cap there,
since the object heights are unknown before the estimate runs.
